Virtually all weight loss diets to varying degrees focus on either calorie reduction or the manipulation of the consumption of one of the three essential macronutrients (proteins, fats, or carbohydrates) to achieve their weight loss effects.
Ketogenic diets are a team of “high-fat, moderate protein” or “high-protein moderate fat” but suprisingly low-carbohydrate diets. The phrase ketogenic basically refers to the increased production of ketone bodies occasioned by the elevated rate of lipolysis (fat breakdown). Ketones would be the acidic by-products formed during the intermediate break up of “fat” into “fatty acids” by the liver.
The first groups of ketogenic diets were actually developed dating back to the first 1920s from the Johns Hopkins Pediatric Epilepsy Center and in addition by Dr. R.M. Wilder of the Mayo Clinic to treat youngsters with difficult to control seizures. The diets were made to mimic the biochemical changes that occurred during periods of fasting, namely ketosis, acidosis, and dehydration. The diets involved the intake of about 10-15 grams of carbohydrates per day, 1 gram of protein per kilogram bodyweight of the patient and the remaining calories produced from fats.
Today, the promoters of ketogenic diets are strongly from the view that carbohydrates specially the high glycemic index ones would be the major reasons why people put on weight. Carbohydrate foods are usually metabolized to produce glucose, a type of simple sugar which is generally thought to be the preferred power source for that body as it is a quicker burning energy. Even though body can break up muscle glycogen (a combination of glucose and water) and fat to produce energy, it however prefers to have it from high glycemic index carbohydrates from diets.
From the macronutrients, carbohydrates are therefore argued to become the main cause of excess weight. This is more so as the increased intake of high glycemic index carbohydrate foods generally causes fluctuating blood sugar levels because of their fast absorption to the bloodstream and which more often than not contributes to the overproduction of insulin. Here is where the situation actually starts.
Insulin is a hormone that regulates blood sugar levels and for that reason repair of the vitality in/energy out equation in the body which rules body weight. Excess quantities of glucose inside the bloodstream causes the excessive secretion of insulin which leads to the storage in the excess glucose within the body as either glycogen in liver and muscle cells or fat in fat cells.
One purpose of ketogenic diets is therefore to reduce insulin production to the barest minimum by drastically reducing carbohydrate consumption while using fats and proteins to supplement the body’s energy requirement.
Regardless of the ability of ketogenic diets to reduce insulin production, their main objective is ultimately geared towards inducing the state ketosis. Ketosis can be thought to be a disorder or state where the rate of formation of ketones produced by the break up of “fat” into “essential fatty acids” by the liver is more than the capability of tissues to oxidize them. Ketosis is actually a secondary state of the entire process of lipolysis (fat break up) and it is a general side-effect of low-carbohydrate diets. Ketogenic diets are therefore favorably disposed to the encouragement and promotion of ketosis.
Prolonged periods of starvation can certainly induce ketosis but it is also deliberately induced by making use of a low-calorie or low-carbohydrate diet with the ingestion of considerable amounts of either fats or proteins and drastically reduced carbohydrates. Therefore, high-fat and-protein diets would be the weight reduction diets employed to deliberately induce ketosis.
Essentially, ketosis is a very efficient type of energy production which fails to involve producing insulin since the body rather burns its unwanted fat for energy. Consequently, the thought of reducing carbohydrate consumption does not only reduce insulin production but also practically forces our bodies to lose its fat deposit for energy, thereby making the use of ketogenic diets a very powerful method to achieve rapid weight reduction.
Ketogenic diets are created in a way they initially force our bodies to exhaust its glucose supply and then finally change to burning its unwanted fat for energy. Subsequent food intakes after inducing the state ketosis are made to maintain the ketosis process running by appropriately adjusting further carbohydrate consumption to provide only the basic quantity of calories necessary for the body.
For example, the Atkins Diet which is obviously the most popular ketogenic diet aims to assist dieters achieve just what the diet calls the individual’s Critical Carbohydrate Level for Maintenance (CCLM) – a carbohydrate consumption level hpubkc the dieter neither gains nor loses weight anymore.
In 2003, the Johns Hopkins treatment center came up with a modified version from the Atkins Diet protocol to take care of a group of 20 youngsters with epilepsy. Right after the treatment, it absolutely was observed that two-thirds experienced a substantial decline in their seizures while 9 had the ability to reduce their medication dosages and none developed kidney stones.
Furthermore, there are ongoing scientific studies from the National Institute of Health (NIH) concerning the strength of the classic ketogenic diet as well as the modified versions from the Atkins Diet in assisting people to lose weight and also in the treatment of epilepsy. It is equally interesting to notice that the National Institute of Neurological Disorders and Stroke (NINDS) is performing studies on the effect of ketogenic diets and also formulating medications that will be able to make the same impact on weight reduction.
